I have a new Aqualink RS4 Main Power Center PCB and a used RS8 PCB for sale on Ebay and having listed them as a "lot" I'm concerned that the boards might not be interchangeable. Both PCB's are 6474 rev G boards. The new RS4 PCB has an ALRS4 PorS PPD installed and the used RS8 PCB has a ALRS8 P&S PPD in it. When listing these two boards and bezels together I intend to provide the buyer with a PPD removal tool so that the new RS4 PCB can be upgraded to an RS8 with the ALRS8 PPD swapped from the used board. As far as I know... both the new and used PCB's are good but I'm a fish out of water with this stuff (my girlfriend's husband passed away - an electrical contractor in the pool business and left her with a bunch of Aqualink components).

Any input would sure be appreciated. Thanks, Steve
